A friend and I won a weeklong ski trip in Chamonix this March. Yay!

I like to ski and fully intend to do so as much as I feel like. But for the days/parts of days I don't feel like skiing, what do people recommend? I'm up for walking around town, taking the train elsewhere in the area for short day trips- anything.

We will be staying in Geneva for the last night of the trip, so I don't need to go there beforehand.

Thanks for any ideas.
